COMPOSITE RAILWAY-TIE.

Application filed February 9, 1920.

To all "to/tomit may concern Be it known that I, ALBERT REVERT, a eiti- Zen of the United- States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Composite Railway-Ties of which the following is a specification.

This invention relates to sectional or composite timbers for use as railway ties and has for its object to simplify and improve the construction of such articles.

Incarrying out this object, I make use of small pieces of waste lumber and prefer ably employ a series of comparatively narrow longitudinal strips laid side by side and held together by the use of obliquely extending dowels, the individual strips before assembling being first treated with pitch or tar to prevent early deterioration.

One form which my invention may assume is exemplified in the following description and illustrated in the accompany ing drawing in which Figure 1 shows a plan view of a tie constructed in accordance with my invention Fig. 2 shows a side elevation of the same Fig. 3 shows a sectional view taken on the line 83 of Fig. 1.

In the present. form of my invention, a series of longitudinal strips 10 laid side by side go to make up the main portion of the tie. These strips are preferably each of a height corresponding to the full height of the tie and also of a length corresponding to the full length of the tie. Near each end of the tie I arrange a short strip 11 at each side. said short strips adding to the width of the completed tie at the place where the rail rests thereon. The said strips 10 and 11 are held together by means of obliquely extending dowels 19., adjacent dowels being oppositely inclined and alternate dowels be ing near the top of the tie and intermediate dowels being near the bottom thereof so that they are staggered in a vertical plane as best seen in Fig. 2. By reason of the oblique disposition of the dowels, the individual strips are securely bound together and effectively held against buckling due to warping.

The ends of the ties, where the short Strips occur, are preferably fitted each with Specification of Letters Patent.

Serial No. 357,487.

a tie plate 13, having prongs or projections 14 to enter the individual strips and end flanges 15 to fit over the corners of the tie and engage the sides of the short strips 11. The tie plates 13 serve as bearing surfaces for the rails and in addition they act to further bind the individual strips together.

Before assembling the individual strips into the form of a railway tie, I treat them with pitch or tar. By so treating the individual strips before laying them, the pitch or tar will permeate evenly throughout said strips and thus the completed tie will be well preserved against rotting or deterioration. The short strips 11. serve to increase the width of the tie beneath the rails and allow the tie to be made narrower intermediate the ends. The obliquely extending dowels will securely retain the individual strips together and prevent any tendency to separate the same or buckle. By this manner of constructing a tie, I am enabled to make use of waste material from a sawmill and also to provide a tie of greater longevity than a solid tie.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 7 1'. A composite railway tie consisting of a series of longitudinally extending comparatively narrow sections laid side by side and a plurality of dowels passing obliquely through said sections to retain them together, said dowels being oppositely inclined.

2. A composite railway tie consisting of a series of longitudinal strips laid side by side to form a tie of the desired length and width, short strips at opposite sides of the tie near the ends thereof to increase the width of the tie underlying the rails, and a plurality of dowels for securing the strips together, said dowels extending obliquely through the strips and being oppositely inclined.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
